Abstract

The portable highway barrier of the present invention comprises an elongated barrier body made of lightweight material and having an open cavity therein. The barrier includes an elongated vertical channel at one end and an elongated vertical rib at the opposite end so that a plurality of barrier bodies can be placed in end to end relationship with the rib of one body inserted into the channel of the adjacent body. The barrier can be filled with water or other fluid material once it has been transported to the construction site.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A portable highway barrier comprising: an elongated barrier body made of lightweight material and having a bottom wall, opposite end walls, a top wall, and opposite side walls, said top wall having a width less than said bottom wall, said side walls each having an upper end connected to said top wall and having a lower end connected to said bottom wall;   said lower ends of said side walls being substantially farther apart than said upper ends of said side wall;   said body having a hollow cavity therein extending along substantially all of its length;   a fluid material being contained within said cavity;   said top wall having a fill opening therein providing access to said cavity for pouring said fluid material into said cavity;   at least one of said end walls having at least one drain hole therein located adjacent said bottom wall for permitting the removal of said fluid material from said cavity;   a fill cap removably inserted within said fill opening;   a drain cap removably inserted within said drain hole;   one of said end walls having a continuous vertical channel extending between the bottom wall and top wall and axially inwardly therein, said channel having a cross sectional configuration of predetermined shape;   the other of said end walls having a continuous vertical rib extending between the bottom wall and the top wall and axially outwardly therefrom; said rib having a cross sectional configuration corresponding to said predetermined shape of said cross sectional configuration of said channel, and   a second barrier body identical to said first mentioned barrier body, said first and second barrier bodies being placed in end to end relationship with said vertical rib of said first barrier body being matingly inserted into said vertical channel of said second body for retentively holding said first and second bodies in longitudinal alignment and against lateral side-to-side movement, said end walls of adjacent barriers abutting one another so as to engage and cover the drain caps on the adjacent barrier.   
     
     
       2. A portable highway barrier according to claim 1 wherein said cavities of said first and second body members have in cross section an upper portion and a lower portion, said lower portion having a width substantially greater than said upper portion whereby the center of gravity of said fluid material within said cavity is located adjacent said bottom wall.
